I've recently got a 32G micro SD card for my birthday :-D I'd like 2G vfat, and 30G EXT4. The reason for something non-vfat is for special character file name support.
I partitioned the card in Linux, and it appears to mount the vfat partition once back on the phone automatically, which is fine. I'm having trouble with the EXT4 partition though.
Firstly, when I use busybox fdisk -l /dev/block/mmcblk0 I get a whole bunch of partitions I didn't create, and the primary partitions all say they end outside cylinder boundaries. I've then noticed that the vfat partition is mounting from /dev/block/vold/<major:minor>. I've ended up feeling a bit lost.
I'd like to to be able to complete the following:-
a) determine if fdisks output is a problem with the formatting; and what I should do to rectify this.
b) how to mount the EXT4 partition, and really how to have it automount on boot.
If I can get those 2 questions answered, I think I'll be fine.
Regards,
Jon

YOU CANT OPEN A THREAD TO ASK A QUESTION !!!!!!!!!!!! GO TO THE RIGHT SECTION AND ASK YOUR QUESTION!!!!!!!!!!!!
Creating question threads in the Development section is a no-no.
You have a Questions & Answer section purely for Questions.
Consider this a friendly reminder, you will not get another.

Excellent, I'd love to see the unfriendly reply :-|
2 replies, and question not answered, so still stands. If anyone can help, that would be appreciated.
Many thanks.
So I found a million threads asking about why they can't ln -s or mount the /mnt/extSdCard to /mnt/sdcard or various forms of that. The motivation here is to allow certain apps that can't get about /sdcard/ to be able to see the additional 64GB of SDHC.
What helped was this realization that the android mount command supports bind and one of a few dozen other threads, mostly this one:
http://forum.xda-developers.com/showthread.php?t=1825494
So it appears there are a half dozen ways to make mounts, from using /dev/block/vold/179:97 to using the vold.fstab which mentions a serial or parallel sdcard scheme, which they chose parallel, to all these init.rc monitoring scripts that have to unmount on USB mode, and crazy stuff and a million Directory Bind apps, and int2SD binder / linker apps. It appears this app might do what I am suggesting but I don't think /emmc/ works anymore and I haven't looked into the .apk.
Ok....
1) ODIN over a root injected stock ROM, or otherwise get root.
2) (A) Get yourself any Terminal program like Terminal Emulator and if you are smart you will also get Hacker's Keyboard.
or
2) (B) From any of the programs that will run scripts, you can just make a script.
3)
Code:
$ su -
# mkdir /mnt/sdcard/external
# mount -o bind /mnt/extSdCard /mnt/sdcard/external
Now you can name it whatever you want but since the home is /sdcard/ it has to be under that.
Or, instead of mounting the whole thing, just mount Movies and Music directory
Code:
# mkdir /mnt/sdcard/Music/extMusic
# mount -o bind /mnt/extSdCard/Music /mnt/sdcard/Music/extMusic
Etc.
Now for those wanting to make a script or app to sell for $1.99... There may be real problems depending on where a backup program chooses to backup and it could be recursive.
And just FYI, this ends up inheriting all the same properties from the extSdCard mount params,
ie. /dev/block/vold/179:97 /mnt/sdcard/Music/extMusic vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
Any mounted directory all look identical in mount and the vold must map them out.
Anyways you can write a simple script and hopefully you are mindful of any backups you do if you save backups to the external sdcard and you mount the entire thing. The safest way would be to mount one directory to transfer files or only mount the large media.
It also means you could copy everything from /sdcard/Music to the external and then mount /sdcard/Music to be a directory on the external card. You could remove the ext SDHC and copy files that way and have everything in one place and not worry about wiping it out.
However, I have benchmarked the internal SD appears to be faster on bandwidth benchmarks versus an external Class 10/UHS. On the stock rom the internal is also fuse versus fat32 for the external SDHC (or exFAT for a SDXC card). There is also something in the SD2.0 spec about the 2nd SD only one can have a higher clock bandwidth.

Did you get an error? There is no output of mount unless there is an error.. Did you look in a file browser to see if that folder is now mounted? This only works until reboot, until someone makes an app or script.
Hi,
@joederp thank you very much ! Your tip in so usefull to me with my galaxy note on CM10 ParanoidAndroid ROM.
The only thing I try now to get work is : automaticaly run the script at phone boot. I'm pretty sure I can get it with Tasker, but did not find the trick.
Just use the directory bind app... It works fine on my galaxy tab 2 7.0
Sent from my SGH-T999 using xda premium
Directory bind is a whole different thing that uses CPU and monitors the system and does who knows what.
You can just use any scripting program or I think edit init.rc and add the extra mount commands. copy init.rc to a .bak and edit it.
Thank to all of you !
I found something more appropriate to my needs in this thread : http://forum.xda-developers.com/showthread.php?t=1593615

Will be waiting for first feedbacks, first bugs, or a first perfect (would be rare, even if I am getting a bit used now to Qualcomm devices)
Flashes fine and looks great.
The time is off by 7 hours for me looked in settings for creating a time zone slot, with no success. The screenshot feature is dope but didn't work, gave me tears and not visible screens. Will flash a kernel in a second to test that much out. Will flash a ROM and create a backup later to test more thorough. The screen is what I got from swipe to left for screenshot in recovery.
EDIT: Kernel falshed fine. so all in all no real issues to report as it works as a recovery should, all but testing nandroid and restoring.

It sure was and time is correct now, I like the brightness settings also, lots of goodies in there. I'll report back later tonight if no one else does on nandroid and such.
ill try it out im using twrp recovery so itll be fun to try something new lol
omg! its touch enabled
and i like the color at first the layout is a win for me so far and ui is to
great job
clock is working changed to my time zone with daylight savings time fine
omg just found out i can you my home back and menu in it
im having fun playing with it im easy to entertain lol give me a break
ok new favorite recovery lol im hooked lol
I do not expect any issue with nandroid backups as it was largely debugged now on other devices
However:
- Mount USB storage works?
- exfat is ok?
- A last important point: when you boot into recovery, /system is mounted or unmounted? To see this, go into Mounts and Storage menu after you booted in recovery. /system should show (mount) and not (unmount)
I ask this to tune things if needed as this is completely repacked around stock ramdisk and kernel to enable exfat mainly
My stuff is fat32 so I can't help there... system is not mounted it shows mount/ system
Just booting into it and scrolling through some of the options was a treat within itself. Don't have much more to say (that hasn't been said already) but I'm glad we're able to have such a refined recovery. I'll let you know if I bump into any issues, as I tend to not stay in recovery mode for too long (when I actually have something to flash, etc. I'll test more). Thanks!

I was able to install it perfectly with Odin with the only difference from your installation instructions being that the phone rebooted into normal mode, so I just entered recovery mode via Rom Toolbox.
I am unable to access an external 64GB SDXC formatted as exFat. I tried to mount /external_sd and /sd-ext and neither one worked. I don't know if this is relevant but the normal mount point for the external SD card on the Galaxy S3 is /mnt/extSdCard.
The aroma file manager doesn't see the external card either.
Everything else seems to be working though I haven't tried to do a backup or a restore.
Thanks for your help...
Love the UI! Very easy to navigate. Everything seems to be running smoothly so far. Installed a few AOSP and TW ROMs successfully. Kernels I've tested are BMS, KT747, and LK. All were successful as well.
EDIT: Backup and restore options seem to work just fine. No issues with Mounts or storage I'm on a fat32 card so I can't test exfat unfortunately. Will let you know if anything comes up within the next day or 2.
Thank you very much for sharing this. It is pretty dope.
Thank you all
Will wait a bit more for reports about exfat
Some 64Gb cards always caused issues on some phones, mainly if they were not formatted as they should (primary partition and default block size)

When I had problems with the early exfat drivers from Samsung, I reformatted the card as Fat32 and ran with that for some time. After installing an update from Samsung/T-Mobile where the exFat issues were fixed I used the following procedure to convert the card to exFat:
1. Copied all data from the card to a PC via a card reader.
2. Deleted all partitions from the card using a partition manager on the pc
3. Installed the card into the phone and let the phone partition and reformat the card.
4. Copied all data from the PC back to the card via a card reader.
5. Re-installed the card into the phone.
It has been several months since I converted the card back to exFat and I have had no problems with app on the phone accessing the card. This include Nandroid Manager, Online Nandroid and Titanium Backup as well as all of the normal Android utilities.
The partition information is:
Partition Type: Primary
Psttition Type Id: 0x0C
File System: exFAT
Serial #: 0
First Physical Sector: 2048 (Cyl: 0, Hd:32, Sect: 33)
Last Physical Sector 124735487 (Cyl: 7764, Hd: 108, Sect: 24)
Total Physical Sectors: 124733440 (60905.0MB)
Physical Geometry: 7764 Cyls, 255 Hds, 64 Sects.
That's the best that I could do on short notice. I am trying to find a utility that will give me more information under Windows 7.
Thanks again and again...
Mike
P.S. If I can help with some testing or programming, please let me know. I'm fighting learning java but I am pretty good with C/C++ and assembler.

Sadly, without a recovery log or even better a dmsg log, I cannot help a lot
exfat drivers are from /system/lib, so the ones used by your ROM. They are not bundled with the recovery as that causes issues for some
can you try this in adb shell:
Code:
mount -t extfat /external_sd
Give the error message if it fails
If it fails, try this
Code:
mount /system
insmod -f -v /system/lib/modules/exfat_core.ko
insmod -f -v /system/lib/modules/exfat_fs.ko
mount -t extfat /external_sd
Give output of these command lines if they do fail

Hi,
I have a Samsung Galaxy Note 2 (SGH-T889). I found a script online which had instruction to execute with script manager (SManager). The file is called app2sdNote2.bin. When I run SManager and located the script, I select Su and Boot. When I select Run, SManager just hangs forever until I kill the process. The grant message never appears. I would like to run the script to use my 64 GB memory card as the default storage. Any help is greatly appreciated.
#!/system/bin/sh
#extsd2internalsd is a modification that allows to switch internal sd to external sd and viceversa. With this you can use default internal sd only for app storage #and the external sd to store all apps resource and all others stuff. The resut is a very big increase of installable apps on gs3

If you're using a TW rom, check the Saber Kernel thread, the version of the script that works with it is posted there (ver 3 I think). I don't think there's a version of the script for AOSP roms though. Hope this helps.

can't mount /data and /sdcard
Hi
After following the instructions on how to increase the data and sdcard partitions, they now refuse to be mounted. fdisk /dev/block/mmcblk0 just gives an error message that mmcblk0 is not avaliable. In TWRP I can't format or change the file systems either, "unable to mount '/data" and "unable to mount storage". Anyone have any ideas? TWRP 2.8.4.1 just to be clear on that.
I just run all the steps to migrate to F2FS. But get stuck on SONY bootlogo..
Im running:
- twrp 2.8.4.1
- nAOSP ROM 5.1 b22
I migrated data/cache/system/sdcard..
I then tried format everything, change data/cache/system/sdcard to f2fs and adb push rom on my sdcard and installed again. It worked, but I noticed that (only) /system was ext4 again. So I tried the migrate step for /system again, but guess what?
Stuck at sony bootlogo..
So currently I have formatted back everthing to ext4 again, installed nAOSP ROM again. It works, but I seems I cannot change anything on my sdcard.. The 'usual folders' are not there, and when I want to download or change something I get an error.. I tried running the commands in Terminal Emulator:
chown -R 1023.1023 /sdcard
chmod -R 770 /sdcard
But when I try run 'chmod -R 770 /sdcard' I get a permission denied. I also tried running under root priveleges with the su command.. but still I get permission denied...
Can someone help me?

I would recommend flashing stock ROM once and then migrating to f2fs then. This should clear out most of Your problem's.
Yeah apparently my internal /sdcard was read-only. But I flashed stock JB ftf with flashtool, after second boot it gave an internal memory error and asked if I wanted to reformat. I clicked yes, and now I can read/write it again. I think Ill hold back with changing my filesystem for now..
thanks.it work for me on nAOSProm for Xperia S rom
i'll Migrate filesystem to F2FS (/sdcard /data and /cache) +10 very very smooth xD
thanks. for solution.
So I have formatted to f2fs everything except /system...is this the good way to go?
I can't feel any difference...

Yes /cache, /data and /sdcard can be formatted with f2fs.
Performance gain is about 20 % in I/O operations - reading/writing to f2fs partitions, and about 5% overall.
You can search for File System Performance F2FS vs EXT4 on this forum for more info.
